Door and window sash



"Feb. 13, 1940. H A. GERLAND 6 DOOR AND WINDOW. SASH Filed Jan. 5, 1939 2 Sheets-Sheet 1 Patented Feb. 13, 1940 UNITED STATES PATENT OFFICE t 5 Claims.

The present invention relates to metal door and window sashes and is particularly adapted for use with either glass or screen panels. It is not intended, however, that the frame be limited in any way to the use of these materials, as any similar material'would be equally adaptable to the frame.

The primary object of the invention is to provide a metal frame which can be easily and quickly assembled in various sizes.

Another object of the invention is to provide a frame, in which both a solid and flexible panel may be equally as well secured therein.

Still another object of the invention is to construct the frame from a single sheet of metal, which would eliminate seams and similar objectionable edges.

While several of the objects of the invention have been specifically set out above, other objects will appear from the specifications taken in connection with the drawings which form a part of this application and in which:

Fig. l is a fragmentary view of a disassembled frame and a pane of glass in perspective.

Fig. 2 is a fragmentary view in elevation showing the frame and pane assembled.

Fig. 3 is an end view of the frame and glass pane as shown in Fig. l. I

Fig. 4 is an assembled end view similar to tha shown in Fig. 2.

Fig. 5 is a disassembled view of the frame and a screen similar to that shown in Fig. 1.

Fig. 6 is a. fragmentary view in elevation showing the frame and a wire gauze assembled similar to that shown in Fig. 2.

Fig. 7 is a disassembled end view of the frame and screen. 7

Fig. 8 is an-end view of the frame and screen showing the first step in assembling the two.

Fig. 9 is a view similar to Fig. 8 showing the second step in the assembling of the frame and Fig. 13 is a sectional view taken along the linel3--l3 of Fig. 2.

Referring now in particular to the drawings, the present embodiment of the invention comprises a frame made from a single metal sheet. The frame is comprised principally of parallel side sections 20, 2d and edge sections 2e and 2].

A recess 4 is formed in the outer edge section 2e for receiving a sash holding and guiding member secured to the door or window casing, which is not shown in the drawings. The opposite edge 2) of the frame has theedges 6 and 6' of the metal 5 sheet turned inwardly toward the recess 4. The recess extends inwardly between the parallel walls 20 and 2d of the frame and toward the edges 6 and-. 6 'to approximately one-half the; distance of'th'eside sections. 10

At the end joints. one end of the frame at M is cut atan angle of approximately 45 degrees (that is; in a right angle joint), while the corresponding end 2b of the frame is cut at right angles to the length of the frame. Within the recess 4 is a small block 8 having an aperture therein, and located between the inturned edges 6 and 6 and the outer side walls of the frame are similar blocks l0 and Ill. The 45 degree angular section of the frame 2a is adapted to fit over the corresponding end 2b and be clamped together by a suitable single screw J2, which is threaded into one of the blocks in, or ID.

Referring to Fig. 1 in which a solid panel I! is secured, there is provided for use with the 86 frame a U-shaped clamp H, which is adapted to fit over the open end members B and 8' of the frame for increasing the pressure of the frame upon the glass panel IS. The closed end of the U-shaped clamp is adapted to rest against, or near the inward edge of the recess 4 as shown best in Figs. 3 and 4. This clamp may be in a singlepiece as shown in Figs. 1 and 5, or it may be in smaller sections, depending upon the most convenient size to use.

Fig. 2 shows the assembled frame and glass pane I5. The frame provides for considerable tolerance in fitting the pane within the open .edge 21' as the position of the edge of the glass may vary between the portion ll of the U-shaped member I! and a point just inside the open end of the frame. The glass, however, to give the best results, should extend to a point near the portion |4 of the member ll as shown best in Fig. 4, but as has been stated before this is not 4,5 absolutely necessary. If the glass is slightly smaller, the spring in the U-clamp has sumcient gripping effect on the inturned frame portions 6 and 9 if substantially within the edge of the opening to support the glass.

Referring to Fig. 5 the frame structure is the same as that explained in detail in Fig. 1. It has been mentioned hereinbefore that the frame is adaptable to accommodate also a wire screen. In using a screen in conjunction with the frame. a a

extended member 8 or 8' of the frame as shown best inFig. 10. The sides of the vti-shaped member extend parallel with the edges of the frame and its central portion 200 extending parallel with the inturned edge portions 6 and In assembling the frame and screen, the procedure is best shown in Figs. '7 to 10. First a small portion Zia of the screen adjacent its edge is bent at right angles to the main section 2|, as shown in Fig. "L- The frame is slightly opened as shown in Fig. 8 and the screen inserted into the opening. At this time the U-shaped member .20 is inserted also along with the screen, as shown in Fig. 9. When the member 20 has beeninserted to the point where the side Ila comes in contact with the end of the frame 2, the frame is pressed together, or it springs together under its own springing action and locks the screen within. the open. end of the frame and about one side of the U-shaped member 20, as shown in Fig. 10.

Referring in particular to Fig. 12, the frame may be made in orderthat it may adjustable by telescoping a section of the frame upon a corresponding section. It will be noted that both the frame sections are shaped substantially alike. one being slightly smaller than the other.- Frame 2 in this instance-is adapted to fit over frame 3, which is slidable on the inside of frame 2. The recess 3' of the inner frame 3 is arranged adjacent the open edge of the frame 2 and has an action similar to the U-shaped member I on the inturned edge members ,8 and 5'.

With a sash frame of this construction, the

frame may ,be made in: long .lengths by comparatively. cheapv methods. The user may obtain these lengths and cut them to the desired size and fit them together by the. simple method set forth herein. Practically any size and-shape frame may be made from this framing. The

shape may be varied by changing the angle of the section cut at 2a and 2b. The blocks 8, ill,

and I0 are furnished separately and are inserted at theioints as shown and described above.-

. In order to insert the screw. l2, it is necessary to punch or drill the proper hol'es as shown at l1 and i1 through the frame members. block member inserted on the side of the frame opposite the head of the screw- I2 is threaded to. receive the screw thread of .thescrew it. With this arrangement it is easily understood that when the screwis tightened the sidesof the frame will be drawn togetherand spaced apart by the block members 8, i0, and I 0' to form a comparatively tight Joint.

While the invention has been illustrated and describedin a particular form, it is not intended thatthe same be limited to this particular description of use, as the scope of the invention is best defined in the following claims.
